void set_cursor_pos(double pos_x, double pos_y)

Set the current cursor position.

Parameters

  • pos_x – the current x-coordinate of the cursor

  • pos_y – the current y-coordinate of the cursor

std::array<std::int64_t, 2> get_cursor_pos() const
std::array<double, 2> calculate_cursor_position_delta()

Calculate the change in x- and y-position of the cursor.

Returns

a std::array of size 2 which contains the change in x-position in index 0 and the change in y-position in index 1
